Favourable weather conditions across Northern Europe enabled amateur radio enthusiast Dr. Jari Korhonen to pick up our FM signal, normally received only in Berlin and Brandenburg, and he has sent us a recording to prove it.

The ionosphere normally refracts radio signals back toward the Earth’s surface. But in exceptional weather conditions, “E-skip” allows signals to bounce off smaller clouds of unusually ionized atmospheric gas at altitudes of around 90 to 160 km.
